As both an educator and psychotherapist the information offered in just the first chapter is useful to better understand the "why" and "how" our brains work. This information can map the pathway to change; change our habits and change our lives. I often request that my client's simplly read the first few chapters so that we can use this information, along with Dr. Porges work in Poly Vagal Therory to support behavior change, better regulate our emotions and offer coping skills to build stress resileince.
